In an electrophilic addition reaction of olefins, the stability of carbocations plays a crucial role. Consider the compounds P and Q that can undergo such reactions with different reagents. With reference to the above reactions, the correct statement(s) is(are):

Options

1. AIn the HBr addition, the rate of the reaction is faster for Q than for P .
2. BHBr addition to P gives an equal mixture of enantiomers as a major product.
3. CP reacts with diborane followed by oxidation with H ₂ O ₂ / NaOH gives racemic alcohol as a major product.
4. DReaction of P with O ₃ followed by treatment with Zn / H ₂ O gives methyl formate and formaldehyde.
